ADJUSTABLE SCREEN AND WINDOW FOR AUTOMOBILES Filed May 28I 1958 2 Sheets-Sheet 2 59 me/wm Patented Mar. 14, 1939 UNITED STATES PATENT OFFICE ADJUSTABLE SCR-EEN AND WINDOW FOR AUTOMOBILES 2 Claims.

This invention relates to automobile windows and the general object of the invention is to provide means whereby a window may be raised or lowered or a screen raised or lowered or both raised or lowered at the will of the occupa-nt.

Another object is to provide means for positively shifting the screen and window and holding them in adjusted position.

The invention is illustrated in the accompanying drawings wherein:

Fig. 1 is an inside elevation of a window casing such as used for automobiles, showing the screen closed.

Fig. 2 is an elevation of the window casing with the inside plate removed, showing the screen raised and the glass pane lowered.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 4 is a vertical section on the line 4--4 of Fig. 3.

Fig. 5 is a section on the line 5-5 of Fig. 2.

Fig, 6 is a section on the line Ii--I of Fig. 2.

In these drawings I have illustrated my invention applied to the door of an automobile, and the metallic casing of this door is designated generally II). The window opening is designated I I, the lower edge of this window opening being dened by an inwardly and upwardly extending flange I2, the ends of the window opening having inwardly extending anges I3. Disposed within the metallic casing of the window is a support-ing frame for the window which may be made of wood or other suitable material. This supporting frame has side members I4 which are grooved at I5 for engagement with the margins of the glass pane I6. Inward of this groove I5, the members I4 are formed with the groove I1 for engagement with the screen designated generally I3. The curved upper element I9 of the wooden frame is correspondingly grooved for the reception of the upper edge of the glass pane and the upper edge of the screen. The base of this frame is designated 20.

For the purpose of operating the glass pane I6, I provide a vertically disposed screw 2i, whose lower end is supported in a pair of spaced plates 22 and 23. Between these plates and carried by the lower end of the screw 2| is a gear wheel 24. This meshes wth'a gear wheel 25 and the gear wheel 25 in turn meshes with a gear wheel 26 having the upper ends of the teeth beveled to constitute a beveled gear wheel.

Mounted between plates 21 and 28 is a gear wheel 29 having beveled gear teeth which mesh with the gear Wheel 26 and this gear wheel 29 in turn meshes with a gear wheel 3B of much larger diameter mounted between the plates 21 and 28. The shaft 3l of the gear wheel 30 extends through the inside plate 32 of the door casing and is pro-v vided with a crank handle 33, thus the train of gears 30, 29, 2B, 25 and 24 may be rotated in either direction by rotating the handle 33 in either direction. Clamped upon the lower edge of the glass pane I6 is a traveling nut 34 having threads engaging the threads of the screw 2i. It will be obvious now that by rotating the screw 2I in one direction or the other, that the glass pane may be slid up or down to a closed or an opened position, as desired.

The screen I8 is embraced at its margin by a metallic frame 35 and mounted upon th-e lower edge of this frame is a traveling nut 36 of the same character as the nut 34. This is. engaged by the vertical screw 31 in turn driven through the train of gears 38, 39, 40 and 4I, the gear wheel 4I being relatively large and having its shaft 42 extending through the rear plate of the window casing and provided with the crank handle 43. The gear wheels 38, 39, 40 and 4I are of precisely the same` character as the gear wheels 24, 26, 21 and 30, but inasmuch ras the screen frame operates inward of the glass pane and inasmuch as the screw 31 must be set inward of the screen frame, there is no necessity for an intermediate gear wheel such as the gear wheel 25. It will be seen that the inwardly extending flange I2 of the outer casing plate will extend inward over th-e upper end of the mechanism for lifting the glass pane and to a point nearly touching the glass pane, and that the flanges I3 will also extend inward nearly to the groove I5.

The operation of the mechanism is obvious from what has gone before. By rotating the handle 33, the glass pane may be raised or lowered and by rotating the handle 43, the screen may be raised or lowered. By this means, both the screen and the window pane may be raised or both lowered, or one raised or the other lowered. It will be likewise noted that this mechanism is not liable to jam, that it is very powerful because of the screw action, and that the window or screenv will be held in any adjusted position against movement either up or down.

It will likewise be noted that in case of breakage, the window pane or the screen frame may be readily removed and replaced. f

What is claimed is:

l. In a structure of the character described, a body formed to provide a window opening and a chamber lying beneath said opening, the lower part of the window opening forming a sill separating it from said chamber, said sill having a slot formed therethrough and extending the width of the opening, a closure member for the window opening, comprising a ilat body of the same edge contour as the opening and adapted to be movedV vertically through said sill slot into the window opening, a screw disposed vertically within the chamber at one side of said slot, a nut carried by said closure bodyand threaded upon said screw, said screw being supported for rotation, a spur gear carried upon the lower end of said screw, a kbeveled gear mounted adjacent the spur gear for rotation on an axis parallel with the screw, said beveled gear having radial 'teeth meshing vwith the spur gear, a second beveled gear in mesh with said rst beveled gear and supported at one side of the screw for rotation upon an Yaxis perpendicular to the screw, said second beveled gear having radial peripheral teeth forming a spur gear, a spur gear Vrotatably supported above andrin mesh with the spur gear `teeth of the second beveled gear, and crank means i width oi' the window opening, a flat closure member having a peripheral contour corresponding to the outline of the window opening and movable vertically through said slot fromrwithin the chamber to closing position with respect to the opening and vice versa, a plate member disposedV in the lower part of said chamber in spaced parallel relation with the bottom wall thereof, said plate member including a vertical side portion disposed in spaced parallel relation with a side wall of the chamber, a screw disposed vertically within the chamber and having a lower end portion extending through said plate, a spur gear upon the lower end portion of the screw between the plate and the bottom wall of the chamber, a combined spur and beveled gear mounted for rotation between the plate and bottom wall and having the spur portion engaging said spur gear, the beveled portion of the combined gear extending into the area between the side portion of the plate and the adjacent wall, a combined spur and beveled gear mounted lbetween said side portion of theV plate and the adjacent wall for rotation on an axis perpendicular to the screw and having the beveled portion thereof meshing with the beveled portion of the rst combined gear, a spur gear rotatably mounted between the side portion of the plate and the adjacent wall and meshing with the spur gear portion of the second combined gear, crank means connected with said'last gear for effecting rotation of the same, andra nut secured to the lower part of said closure member and threaded upon said screw.
